【摘要】 太原市美术馆是现代非线性建筑艺术发展的一次大胆尝试,其主体结构为螺旋上升的错层结构,且各层的平面及外形均为不规则的多边形。主体结构平面严重不规则,主轴关系不明确;由于错层和空间的不断旋转变化,竖向构件存在大量的转换,结构共用长短柱情况较普遍,竖向薄弱层及薄弱节点较多;在顶层还有一大悬挑结构,悬挑的最大长度达22.0m。主要介绍本工程的概念设计思想,对非线性建筑结构的各项不规则性采取性能化设计方法和措施。采用性能化设计的方法,使非线性建筑的建造成为可能,且满足抗震规范三水准设防的安全要求。相关内容可为具有类似复杂结构的工程设计提供参考。更多还原

【Abstract】 Taiyuan Art Museum is a typical nonlinear building.The building was composed of many floors in different heights around the exhibition stream line,which leads to the main structure with characteristic of plane irregularity,vertical irregularity and complex long cantilever structure etc,which makes the structure be an extremely complex building.The steel frame structure combining with braces is adopted to resist the vertical and lateral loads.The structural analysis and design are presented,and the key technique is introduced,including structural system selection,comprehensive seismic analysis,performance based design method etc.Which may be a reference for design of similar projects.更多还原
